Kurková, Dita ; Venkrbec, Václav (referee) ; Nečasová, Barbora (advisor)
The subject of the diploma thesis is the solution of chosen parts of the construction technology project of the 1st phase of the construction „Komplex RD Slavkov, Pod Zlatou horou“. These are 4 semi-detached houses, overall 8 family houses. The work deals with technological regulations for the superstructure including roof, study of the realization of the construction technology project, design of the main construction machines and mechanisms and control and test plan. For the whole construction is elaborated time and financial plan in two variants, namely the gradual and current method of construction, and a detailed schedule for one semi-detached house. The technical report of the building site equipment is completed with the drawings, itemized budget of the building part of the house, noise study and specialization focused on the photovoltaic system, with an alternative solution to use solar collectors. The thesis also includes a case study of construction methods focused on the gradual and current method of construction.
Energy system for energy independent object
Kaňovský, Jiří ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
This bachelor‘s thesis deals with a design of energetic system for energetic independent family house. There are default parameters for the house defined, and an impact of house's placement in nature on thermal energy loss and on thermal energy gain due to solar radiation is described at first. There are daily diagrams of thermal energy consumption for common and heating periods derived in this thesis. An energetic system producing electric energy using photovoltaic solar panels which are placed on the house's roof is designed based on the diagrams. The thesis also introduces basic types of island energetic systems. The objective of this thesis is also a design of energetic system for heating-up (TUV) using a thermal pump, fireplace and solar collectors.
Energy-saving kindergarten building in Trutnov
Lacko, Martin ; Uher, Pavel (referee) ; Blasinski, Petr (advisor)
The aim of this master's thesis is to propose the construction of a new kindergarten with almost zero energy consumption. The building is purposefully divided into three parts, with one part serving as facilities for staff, the second part consisting of classrooms for children, and the third part comprising a speech therapy clinic. The thesis is divided into three parts. The first part focuses on the design of the structural solution, which involves a single-story, without basement structure. Load-bearing vertical structures are made of aerated concrete masonry, and horizontal load-bearing structures consist of hollow precast Spiroll panels. The building's roof is designed as a flat, single-layer, extensive green roof. The second part is dedicated to the design of the HVAC system. A heat pump air/water system is proposed as the source of heating and cooling, with a gas boiler as a bivalent source. The heating of the building will be provided through radiators, except for the classrooms, which will have floor heating. Air exchange is ensured through mechanical ventilation with heat recovery. Additionally, a hybrid photovoltaic power plant on the roof partially supplies the building with electricity. The third part involves an experiment on a ventilated facade, where temperature measurements in the air gap are conducted. The result is a comparison between an open ventilated facade and a closed ventilated facade.
Using renewable energy sources
Vaňko, Adam ; Bátora, Branislav (referee) ; Matoušek, Antonín (advisor)
Thesis deals with the issue of renewable energy sources. It contains the description of their usage at present as well as the possibilities of their installation. When dealing with the individual types of sources the thesis states their advantages, disadvantages and the facts concerning their further development. Technical development brings us new and perspective types of renewable energy sources, the description of some of them can be found in the thesis as well. The second part of the thesis is focused on the solution of electric power supply for a holiday cottage. Authonomy photovoltaic system is suitable for its application. The system is designed to have an ability to supply electrical units in the cottage during the whole year. To be able to consider profitability of the photovoltaic system installation the thesis contains the project of low voltage energy branch connection. This branch line of 1200 m in length is properly designed and the thesis states its capital costs as well. Financial comparison of the photovoltaic system costs on the one hand and the costs of low voltage branch line on the other hand in the next 30 years of usage proves the profitability of the photovoltaic system.
Processing of the project combined solar system
Sučková, Tereza ; Půčková, Helena (referee) ; Kotlík, Josef (advisor)
The diploma thesis studies the elaboration of project about optimization of solar system for all- season service. The aim of the work was to make a proportioning, choosing the right parts and finding the economic and ecologic balance.
Type project of electrical system for family house making use of photovoltaic system
Straka, Michal ; Bátora, Branislav (referee) ; Mastný, Petr (advisor)
This work deals with electro instalation with using photovoltaic system. First we explain the principle functions of photovoltaic panels, the basic concepts and issues of photovoltaic systems. Next, we define the various components of photovoltaic systems. The result of this work will be implemented own proposal for electricity and photovoltaic system on the roof of a house.
Modeling of energy flows in the municipality with battery systems
Řehořek, Tomáš ; Krátký,, Milan (referee) ; Paar, Martin (advisor)
This thesis studies battery systems and possibilities of their utilization together with PV systems mainly for domestic purposes. Furthermore, the thesis deals with the impact of increased number of BEVs on load demand. The aim of the thesis is to simulate and investigate the power flows, within a selected grid, with high levels of PV generation paired with battery systems. The calculation of the power flows is performed in OpenDSS and the input data for the simulations are generated in Matlab. The theoretical part of the thesis describes the technology of the battery systems and how they operate. The thesis also partly touches on the use of battery systems for grid applications. In the practical part, an evaluation of simulations investigating the capability of battery systems to limit peaks of surplus generated energy is performed. As well as that the impact of increased load caused by BEV charging and the possibilities of reduction of this load via use of battery systems is also investigated.

Kindergarten
Frieb, Vilém ; Struhala, Karel (referee) ; Jelínek, Petr (advisor)
The aim of this master project is to design a nearly zero-energy building of kindergarten. The kindergarten is designed as one storey building with capacity of 40 children split into two playrooms. Playrooms are separated and each of them has own sanitary facilities and locker room. Playrooms have large windows with external blinds on the south to provide solar gains. There is horizontal sun breaker above the windows which prevent overheating in summer. Load bearing walls are made of sand lime blocks. Walls are insulated with mineral wool board. Roof ceiling is made of prestressed concrete slabs. The building has a flat extensive green roof. The second task of the project includes design of lighting, rainwater harvesting, HVAC, source of heat and photovoltaic system. The third part is theoretical and includes searching for an ideal source of energy for the building. There are two types of heating compared such as gas boiler and a groundwater heating pump. The main software used for the project is Revit.
